While the summary of the outing may say that "location information is not available," in reality, it is ALWAYS in the description of the outing. Simply click the "more" link at the end of the description.

Questions? Contact the leader who is listed in the activity description (Note: the leader may not be the same as the host)

don’t wait until the night or morning before as all leaders are not "connected" 24/7 (and some don't offer a public cell number)
